Review FAIRCHILD AUTOMOTIVE

The Fairchild KG4028 is a high performance, monolithic microwave integrated circuit (MMIC) designed for use as a frequency multiplier in the X-band frequency range. This device is ideal for applications such as radar systems, satellite communications, and electronic warfare systems where high frequency multiplication is required.

The KG4028 is a third order, Colpitts-type frequency multiplier. It features a wide input frequency range of 4.5 to 5.5 GHz with a multiplication factor of 3x, resulting in an output frequency of 13.65 to 15.15 GHz. The device is designed to be operated from a 12 VDC supply voltage with a typical current consumption of 350 mA.

The KG4028 is fabricated on GaAs technology and is housed in a compact, hermetic TO-46 package. It offers excellent gain of 13 dBm, high output power of up to 3 Watts, and low phase noise of -90 dBc/Hz at 10 MHz offset from the carrier. The device also features good input and output match, ensuring efficient power transfer and minimizing reflections.

The KG4028 is designed to operate over a wide temperature range of -40 C to 85 C, making it suitable for use in various environments. It also offers good stability, with a typical frequency deviation of 50 ppm over the temperature range.

In summary, the Fairchild KG4028 is a versatile and high performance MMIC frequency multiplier suitable for use in a wide range of applications where high frequency multiplication is required. Its excellent gain, output power, phase noise, and input/output match make it an ideal choice for X-band radar systems, satellite communications, and electronic warfare systems.

The Fairchild KG4028 is a high voltage, high gain, and low noise operational amplifier (op-amp) that is commonly used in various electronic applications. Here are some pros and cons of buying this op-amp:

1. High Voltage Handling: The Fairchild KG4028 can handle input voltages up to 15V, making it suitable for use in high voltage applications.

2. Low Noise: This op-amp has a low noise floor, which is essential in applications where the signal-to-noise ratio (SNR) is critical.

3. High Gain: The KG4028 has a maximum gain of 100,000, making it an excellent choice for amplifying weak signals.

4. Wide Bandwidth: The op-amp has a bandwidth of 10MHz, which is adequate for many applications.

5. Low Power Consumption: The KG4028 consumes a relatively low power of 15mW, making it a good choice for battery-powered applications.

1. Large Package Size: The KG4028 comes in a standard 14-pin DIP package, which may require more board space than some other op-amps with smaller packages.

2. Limited Supply Voltage Range: The op-amp requires a dual supply voltage of 12V to 15V, which may not be suitable for all applications.

3. High Cost: The Fairchild KG4028 is more expensive than some other op-amps with similar specifications.

In conclusion, the Fairchild KG4028 is a high-performance op-amp with low noise, high gain, and wide bandwidth, making it suitable for various applications, especially those requiring high voltage handling. However, its large package size, limited supply voltage range, and high cost may be drawbacks for some users.

If you are looking for an op-amp with a smaller package size or a more extensive supply voltage range, you may want to consider other options. However, if your application requires the high voltage handling and low noise properties of the KG4028 and you have the board space and budget for it, then it is an excellent choice.

If you need an op-amp with high voltage handling, low noise, and high gain, and you have the board space and budget for it, then the Fairchild KG4028 is an excellent choice. However, if you require a smaller package size, more extensive supply voltage range, or a lower cost, you may want to consider other options such as the Texas Instruments LM324 or the Analog Devices OP27.
